“…[ 34 ] An even higher reduction in thermal conductivity is observed for the plasma‐enhanced atomic layer deposition (PEALD) grown BTO thin films. [ 35,36 ] Both measurements are not consistent with our first‐principles thermal conductivity predictions. Similar discrepancy between the experimental measurements and first‐principles predictions is also observed in STO, also presented in Figure 4b.…”

“…b) Thermal conductivity of BTO as a function of characteristic length. The characteristic length is equal to film thickness for this work (green squares) and PEALD BTO thin films (blue squares), [ 36 ] and grain size for ng‐BTO thin films (red squares), [ 34 ] ng‐STO thin films (brown triangles), [ 27 ] and ng‐STO ceramics (pink triangles). [ 38 ] The bulk value of BTO measured using a single crystal (black dashed line) is also shown.…”

“…This is observed in recent work during the growth of BTO on a Si substrate where the low thermal conductivity is attributed to mixed amorphous and crystalline phases. [ 35,36 ] Second, the experimental discrepancy can also be accounted for by considering the uncertainties in accurately determining the thermal conductivity of BTO film using TDTR measurement. The measurement is not only sensitive to the thermal conductivity of BTO but also to the interfacial thermal conductances.…”

“…[ 34 ] Subsequent measurements using TDTR also show a similar high average phonon MFP. [ 35,36 ] Therefore, this information about the phonon MFP distribution in BTO is not conclusive in the literature due to the lack of consistency in the quality of grown films and discrepancy in the measured data. Moreover, simulations remain challenging due to either the inaccuracy of the force field in molecular dynamics or excluding the effects of higher‐order anharmonicity in the first‐principles based modeling.…”

Nanosized perovskite ferroelectrics are widely employed in several electromechanical, photonics, and thermoelectric applications. Scaling of ferroelectric materials entails a severe reduction in the lattice (phonon) thermal conductivity, particularly at sub‐100 nm length scales. Such thermal conductivity reduction can be accurately predicted using the information of phonon mean free path (MFP) distribution. The current understanding of phonon MFP distribution in perovskite ferroelectrics is still inconclusive despite the critical thermal management implications. Here, high‐quality single‐crystalline barium titanate (BTO) thin films, a representative perovskite ferroelectric material, are grown at several thicknesses. Using experimental thermal conductivity measurements and first‐principles based modeling (including four‐phonon scattering), the phonon MFP distribution is determined in BTO. The simulation results agree with the measured thickness‐dependent thermal conductivity. The results show that the phonons with sub‐100 nm MFP dominate the thermal transport in BTO, and phonons with MFP exceeding 10 nm contribute ≈35% to the total thermal conductivity, in significant contrast to previously published experimental results. The experimentally validated phonon MFP distribution is consistent with the theoretical predictions of other complex crystals with strong anharmonicity. This work paves the way for thermal management in nanostructured and ferroelectric‐domain‐engineered systems for oxide perovskite‐based functional materials.

Drug-Induced Dyskinesia Treated with Korean Medicine: A Case Report

et al. 2023

Drug-induced dyskinesia is an involuntary muscle movement caused by various dopamine receptor-blocking drug exposure, such as antipsychotics, antidepressants, and antiemetics. Causative drug removal is the main treatment for drug-induced dyskinesia whenever possible because its pathophysiology lacks a universally accepted mechanism; however, the symptoms can persist for years or decades in many patients even after causative drug removal. Herein, we present a case of drug-induced dyskinesia in a 61-year-old female patient who consumed medication for approximately 10 years for her depression, anxiety, and insomnia. Cervical and facial dyskinesia was suggested to be related to perphenazine and levosulpiride administration. The patient received acupuncture, pharmacopuncture, herbal medicine, and chuna treatment for 81 days during hospitalization. The symptoms were evaluated using the Abnormal Involuntary Movement Scale, Toronto Western Spasmodic Torticollis Rating Scale, Tsui's score, and Numeric Rating Scale, which revealed remarkable improvement, suggesting the effectiveness of combined Korean medicine for drug-induced dyskinesia.
